struct pci_host_bridge gained hooks to map/swizzle IRQs, so that the IRQ mapping can be done automatically by PCI core code through the pci_assign_irq() function instead of resorting to per-arch specific implementation callbacks to carry out the same task which force PCI host bridge drivers implementation to implement per-arch kludges to carry out a task that is inherently architecture agnostic. Add map/swizzle IRQs hooks to the xgene PCI host driver to move the IRQ allocation into core code and stop relying on arch specific callbacks.
